NewTek’s TriCaster comes to mind, but that is more of a hardware/software solution, and expensive. Are you talking about something that will assist you in “live” presentation circumstances? If so, I suppose something like the above would be overkill, or a solution, depending on your budget, needs and focus toward expansion in the presentation field.
I suppose, also, that the various PowerPoint-like packages would offer some kind of solution.
Me, unless I am trying to do something “live” I would just create the presentation and burn it to disk, saving myself the extra technodifficulties.
